title: [Diagnosis and treatment of basaloid squamous cell carcinoma of the esophagus].
abstract: OBJECTIVE
  To investigate the histopathological features of basaloid squamous cell carcinoma of the esophagus, and to explore the ways of its diagnosis, differential diagnosis and treatment.
  
  
  METHODS
  The clinical data and pathological features of 23 cases of esophageal basaloid squamous cell carcinoma were reviewed and analyzed retrospectively.
  
  
  RESULTS
  The tumors were mainly located at the middle third segment of the esophagus. The 1-,2- and 3-year survival rates were 60.9%, 21.7% and 0, respectively.
  
  
  CONCLUSIONS
  The basaloid squamous cell carcinoma of the esophagus is highly malignant with poor prognosis. Radical resection combined with radiotherapy and chemotherapy is required.
